它说它无法启动java.sql.datasource..我应该如何启动它

如果使用MySQL，您需要指定实例化的具体数据源：

com.mysql.jdbc.jdbc2.optional.MysqlDataSource

或

另见：

而不是接口javax.sql.DataSource-无法构造，因为异常告诉您：

原因：org.apache.shiro.config.ConfigurationException:无法 实例化类[javax.sql.DataSource]

您还需要在类路径中包含MySQL连接器JAR文件

谢谢您的回答，但即使在我使用上述两个数据源代码时也会出现相同的错误。我还有MySQL连接器JAR文件是..但我通过使用和参考解决了错误

com.mysql.jdbc.jdbc2.optional.MysqlDataSource

com.mysql.jdbc.jdbc2.optional.MysqlConnectionPoolDataSource
